I should mention a handful of q-tips or something similar to scrub and remove rust and excess oil; particularly in the areas of nose edges, driving bands, etc..
You can also do the oil scrub and remove excess with hot, soapy water too; be sure again to wipe out the cavities good, then heat up to cook off the excess water.
I've done both, but usually do the oil scrub/hot pad/lead bath because it provides some seasoning to the iron. Soapy water leaves it nekkid and dry.
